I've looked on other threads to see if another person had the same problem. Turns out a few people did, so I tried what the people suggested but no dice... I've run "Malwarebytes' Anti-Malware" but it didn't take care of the problem.

The problem is, All programs on my computer cannot connect to the internet. I can ping www.google.com through command prompt and get a response but I can't connect to anything with Mozilla, IE, Games, etc.

Another thing is, On Malwarebytes you're supposed to update it, correct? Obviously since I have no connection capabilities I can't do this. I've tried downloading the updates on this computer (backup laptop) and thumb drive them over to my infected desktop and run it, it says, "The database you are using is not supported by this version of Malwareytes Anti-Malware. Download the latest version of the program."


By reading other threads Im pretty sure I'm infected with a DNS changer but I'm not sure. I need some advice... What's the next step?

Hello and welcome
If you cannot use the Internet,you will need access to another computer that has a connection.
From there save mbam-setup.exe to a flash,usb,jump drive or CD. Now transfer it to the infected machine, then install and run the program.
If you cannot transfer to or install on the infected machine, try running the setup (installation) file directly from the flash drive or CD by double-clicking on mbam-setup.exe so it will install on the hard drive.
***
Manually Downloading Updates:
Manually download them from HERE and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.



NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

Please download Malwarebytes Anti-Malware and save it to your desktop.

Fix for the DNS changer
Next you must reset the router to its default configuration. This can be done by inserting something tiny like a paper clip end or pencil tip into a small hole labeled "reset" located on the back of the router. Press and hold down the small button inside until the lights on the front of the router blink off and then on again (usually about 10 seconds). If you donít know the router's default password, you can look it up HERE.

However, if there are other Zlob-infected machines using the same router, they will need to be cleared with the above steps before resetting the router. Otherwise, the malware will simply go back and change the router's DNS settings. You also need to reconfigure any security settings you had in place prior to the reset. Check out this site HERE for video tutorials on how to properly configure your router's encryption and security settings. You may also need to consult with your Internet service provider to find out which DNS servers your network should be using.

Once you have ran Malwarebytes' Anti-Malware on the infected system, and reset the router to its default configuration you can reconnect to the internet, and router.
